Methods of calibration for exposure meters , air kerma meters , air absorbed dose meters and dose - equivalent meters 曝光计空气比释动能测量仪空气吸收剂量测量仪和剂量当量测量仪的校正方法
2.
The large nuclear temperature evaluation would violate conservation of energy , and may lead a negative neutron kerma factor 这就可能使评价核温度太高而导致平均次级中子能量( ? )过大，破坏了能量守恒，而导致了负kerma因子。

The fading correction and its corresponding calculation method were specially introduced in this paper for improving the accuracy of the environment cumulate kerma 为了提高环境累积比释动能的测量准确度，特别介绍了环境剂量计的衰退修正及其计算方法。
5.
The rectangular shape would make the e ' _ ( n ) too large , which can violate conservation of energy and may lead a negative neutron kerma ( kinetic energy release in materials ) factor )过大，从而产生负kerma ( kineticenergyreleaseinmaterials )因子。文档5中的次级中子数据以蒸发谱来描述时，一些核素也出现了负kerma因子现象。

It can be seen from the measuring results that the deviation is litter than 10 . 1 % when the estimate value of the nature radiation ' s kerma is compared to the average value gotten by standard ionization chamber , and the deviation is less than 16 . 2 % when the estimate value of two groups of tlds those measuring radiation in laboratory is compared to the conventional true value in standard radiation field 从参比单位给出的测量结果看出，天然环境辐射比释动能测量的评定值与标准电离室测量的平均值比较，其偏差好于10 . 1 % ，实验室射线照射组两组热释光剂量计( tld )测量评定值与标准辐射约定真值偏差好于16 . 2 % 。
